34
How to dose a PPI
Without barrett's take the lowest dose for the shortest possible duration discontinue in patients without symptoms
35
If a low dose PPI is not effective
increase from once daily to BID follow up or schedule endoscopy If warning signs, endoscopy indicated
36
PPI dosing for Barrett's esophagus
longer term use | maintenance acid suppression to avoid recurrence of symptoms
37
PPIs adverse effects
``` Risk of infection Decreased acid→ decreased protection against bacteria→ C. Diff, other infections Malabsorption *Magnesium*, +/- Calcium, B12, Iron Other risks → dementia, heart disease? ```
38
Monitor _______ while on PPIs
Check Mg periodically +/- yearly B12, bone density
39
Indications for anti-reflux surgery

41
Esophagitis definition
Gastric acid + pepsin + bile → irritation of the squamous epithelium→ inflammation, irritation, erosion, ulceration
42
Types of esophagitis

M>F, 55 years | Found in 10-15% of patients undergoing EGD for GERD
49
Treatment of Barrett's esophagus
PPI→ indefinite use EGD surveillance→ detect evidence of dysplasia Removal
50
2 ways to remove cells of Barrett's esophagus
Endoscopic Eradication Therapy (EET)/Endoscopic Ablation (EA) Thermal or photochemical energy to destroy Barrett mucosa ``` Endoscopic Resection (ER) Remove segment of Barrett mucosa→ therapeutic and quantifies depth of involvement ```
51
2 types of esophageal cancer
Squamous cell carcinoma | Adenocarcinoma
52
Squamous cell carcinoma vs Adenocarcinoma: Epidemiology
Squamous cell carcinoma: urban areas, african american men Adenocarcinoma: caucasians, M>F
53
Squamous cell carcinoma vs Adenocarcinoma: incidence
Squamous cell carcinoma: decreasing Adenocarcinoma: increasing, focus on early detection and prevention
54
Squamous cell carcinoma vs Adenocarcinoma: risk factors
Squamous cell carcinoma: smoking, alcohol, diet low in fruits/vegetables, selenium/zinc deficiency, caustic esophageal injury, +/- HPV Adenocarcinoma: *Barrett’s* → .5%/ year (1/200) progress Smoking, obesity
55
Presentation of esophageal cancer
Progressive dysphagia: solid food→ soft foods→ liquids Weight loss, odynophagia, malnutrition, anorexia
56
Esophageal cancer prognosis
50-80% of patients present with incurable, unresectable, or metastatic disease→ palliative treatment: +/- Chemo, radiation, surgery
57
If a patient has dysphagia...
perform endoscopy! | +/- Barium contrast esophagram
58
Infectious Esophagitis

60
Pill Esophagitis
Medication induced, ibuprofen “gets stuck”
61
Esophagitis Associated with Systemic Illness
Systemic Sclerosis (collagen vascular disease) → poor acid clearing→ Epithelial damage
62
Eosinophilic esophagitis definition
